Which voltage should never be measured directly with a VOM?

Explanation:

When it comes to measuring voltage using a VOM (Volt-Ohm Meter), it is important to note that any voltage over 1000V should never be measured directly with a VOM. This is because VOMs are typically designed for lower voltage ranges and may not be able to handle higher voltages safely.

In the given data, the options provided are 1200 V, 500 V, 800 V, and 100 V. Out of these options, the voltage that exceeds the safe measurement range for a VOM is 1200 V. Therefore, 1200 V should never be measured directly with a VOM.

When dealing with high voltages such as 1200 V, it is recommended to use specialized equipment designed for high voltage measurements to ensure safety and accuracy.
